EUP is a contract Token implemented based on smart contracts. EUP can be used as a medium of value circulation and trading in the film and television media industry and related fields. It can not only be used as a general equivalent for circulation but also for trading and investment. Later, we will develop the Oulian chain into a public chain, allowing every director, singer, actor, and producer to issue their own tokens on the public chain, realizing the monetization of IP values by relying on EUPs massive user base. At that time, data interactions between sub-chains, execution of smart contracts, and exchanges of assets and information data in various stages of film and television production and distribution will all consume EUP, making EUP the transaction medium on the Oulian ecosystem. In the global film and television ecosystem, there are numerous token consumption scenarios involving a wide audience, and the usage volume will be an extremely large number.
